  Hello there, happy holidays. I've been maintaining for 6 years this Dog API that only returned facts. I recently rewrote the project to make it more flexible [1] and I had a blast doing so. This API has been used by a lot of computer science students, as well as bots and other 3rd party services that integrated in the past. The old endpoint receives around 1,000-1,500 requests per day, which makes me happy. The goal is to extend it to make it more interesting and usable, I collect dog data in my spare time. I'm not looking to monetize it, it's just for the love of education. Feel free to use…

  Development teams often struggle with using multiple tools like Postman and Swagger for API design, development, and testing. This fragmented approach leads to outdated API specs and chaotic collaboration. So we built Apidog: a single, unified API platform for team collaboration. It has a beautiful interface that makes it easy to create API spec, generate request data from API spec, validate responses, create mock data, orchestrate test scenarios, and publish API documentation. Apidog = Postman + Swagger + Mock + JMeter.

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
